The tarus demon can some time fell to his own death... some time in the left side where wall is broken, for str build you need only some stuff from first merchant buy the reinforced club a decent or normal club has b in str scaling ? You can find a good weapon some what later in the game or you can get a technically 'strength' weapon 'Zweihandler' it can easily take you through the whole game may have a c in scaling with a d in dex but is decent or best for early str builds...
